Hop plant named YCR Accession No. 5

ABSTRACT

A new hop plant variety is disclosed. The variety is a cultivar of recent origin, used for its bittering and aromatic properties. The new variety is moderately tolerant to powdery mildew and Sphaerotheca. The new variety produces a medium size cone with good pickability and storageability. The cones mature relatively late, and crop yield is 2750 to 3000 pounds per acre (3080 to 3360 kg/ha).

BACKGROUND AND SUMMARY OF INVENTION

This invention relates to a new and distinct variety of hop plant, and more particularly to a new hop plant variety of unknown parentage which was discovered among plants created as part of a controlled breeding program. The new variety has been stably reproduced over successive generations. Discovery of the new variety and initial reproduction by root cuttings was carried out in a research nursery in Prosser, Wash., U.S.A. Subsequent asexual reproduction took place in Granger, Wash., U.S.A.

DESCRIPTION OF THE VARIETY

The new hop plant variety is a cultivar of recent origin, used for its bittering and aromatic properties. The new variety is moderately tolerant to powdery mildew and Sphaerotheca. The new variety produces a medium size cone with good pickability (similar to Nugget, unpatented) and storageability (18% to 20% alpha loss after 6 months common storage). The cones mature relatively late (after Sep. 15 in Granger, Wash., and crop yield is 2750 to 3000 pounds per acre (3080 to 3360 kg/ha).

The following is a detailed botanical description of the new and distinct variety of Humulus lupulus, based on observations of specimens grown in Granger, Wash. during the 1998 growing season.
